Drainage Geocomposites are a full line of technologies used to address drainage requirements for a broad range of construction applications. Prefabricated drains consist of formed three dimensional polymeric cores that are combined with a geotextile filter fabric. The core offers strength and provides a secure flow channel for collected water. The filter fabric retains soil particles while allowing water to freely enter the drainage core.
Unlike pipe and stone systems, drainage geocomposites are manufactured to meet specific physical and mechanical properties that are verified by independent testing laboratories per ASTM standards, ensuring your project will “flow” according to plan. Critical design considerations typically include three basic physical properties - water flow rate, core compressive strength and the fabrics ability to filter soil particles. Most drainage geocomposites have a minimum of 12 times more open area to allow for water collection than traditional pipe and stone systems, allowing for better performance at a lower cost.
